Actually yes, these things and many beyond that are knowable, yet you don't know them. Therefore you only have a sense for a subset of reality, just as you can't see the whole spectrum of light or hear every sound.

But this extreme example is not really relevant for this discussion, at least that's my humble opinion.

You also can't detect the Higgs field, or neutrinos or dark matter and energy, or gravity waves, or really vast amounts of forces and particles that are nonetheless very real. Most of 'reality' is totally invisible to us because it doesn't help us survive.
